STOP-MOTION FOR DOUBLING-MACHINES.

EiPECIPICATION forming part of Letters Patent No. 341,597, dated May 11, 1886.

Application filed Apr-i124, 1885.

To all whom it may concern.-

Be it known that we, JOHN NIGHTINGALE and JOSEPH NIGHTINGALE, both of Paterson, in the county of Passaic and State of New Jersey, have invented a new and Improved Stop- Motion for DoublingMachines, of which the following is a full, clear, and exact description.

Our invention consists in the construction, combination, and arrangement of parts, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 shows a sillcdoubling machine with our invention applied thereto, only so much of the machine being shown as is necessary to illustrate our invention. Fig. 2 is a detailed view showing the receiving-bobbin, means for revolving it, and the ratchet for stopping the bobbin in case a thread breaks. Fig. 3 is a detailed sectional View of the spindles and spools, showing a modification; and

. Fig. 4 is an enlarged side elevation of one of our new gravity take-ups removed from the creel-spindle. Fig. 5 is a perspectiveview on an enlarged scale, showing two of the spools c on their spindles, the take-ups, and a modified manner of connecting acord, d, therewith, the ends of the plate D being broken away. Fig. 6 is a similar view to Fig. 5, but showing a separate cord for each take-up arm.

A represents our new gravity take-up. It is, by preference,composed of the collar a and bent wire or rod a, secured to the collar a. The collar a is made of a size to fit loosely upon the creel'spindles 1) below the spool c. The rod or wire a is bent at right angles, so that the longer arm thereof stands parallel with and a little distance from the spool c, as shown clearly in the drawings, and the rod or wire is formed or provided with an eye, 6, to receive the cord d, that is attached to'the stop lever or pawl f,for stopping the revolution of the bobbin B and spindle B, on which it is placed, in case a thread should break. The several cords d that connect the pawl with the eyes of the take-up arms may be tied to said eyes, or knotted after having been passed through said eyes. These eyes e prevent the cords from sliding laterally on the take-up Serial No. 163,306. (No model.)

arms, thus rendering confusion by tangling impossible. The spindles b may be of any desired number, and are each attached to aplate or bar, 0, that is adapted-to be seen red to the inclined plate D, attached to the main frame E ofthe doubling machine, so that the spindles b will hold the spools c at an angle, as shown in Fig. 1, in the ordinary way. The spindle B isrevolved by the frictioirwheels h i in the ordinary manner, and the spindle is provided with the ratchet-wheel j, with which the abovementioncd pawlf is adaptedto engage in the ordinary manner for stopping the revolution of the spindle B if any of the threads .9 break. It will be observed that the pawlf has a long and a short arm, the long arm extending adjacent to the ratchet-wheel j, andthe cord d or the rod 7:, hereinafter described, is attached to the short arm of said lever. The spools c are placed upon the spindles b, so that the threads unwind from the top of the spools, and the thread is passed first under the wires a and carried thence over the bars B then through the traversing eye 13 to the bobbin B. In unwinding the thread from the spools c the friction of the spools upon the spindles b will cause each thread to lift its take-up A to or nearly to a level with the thread on the spool, as shown in Fig. 8, so that the wholeweight of the take-up comes upon the thread and always holds it taut, and takes up any slack that may occur in the thread by reason of the spool turning too rapidly on spindle c or otherwise. In this manner a regular tension is kept upon the threads, causing them to be wound with uniform tightness upon the bobbin B.

Each take-up A is preferably connected to the end of the pawl f byasmall cord, d, above mentioned, as indicated in Fig. 6. Vhen the weight of the take-up is upon the thread, the cord (1 is slack; but in case the thread breaks the whole weight of the take-up will come upon the cord (1, which will turn the pawl upon its pivot and cause its inner end to engage with the ratchet-wheel j, and thus instantly stop the revolution of the spindle B. In the modification shown in Fig. 5 a single cord d extends through the several eyes of the take-up, and is knotted below each eye, so that, no matter which thread breaks,.the cord IOO d may be readily operated by the falling of a take-up arm. The cord d is of course slackthat is, not under tensionwhen none of the take-up arms rest upon a knot to hold the pawl engaged.

In place of a cord or cords d, we may use a single light'plate or rod, k, attached to the pawl f, and provided with pins or projections 70, one for each take-up A, and arranged below the arm atof each take-up, so that when a thread breaks the take-up will drop upon a pin, 7;, which will draw the plate or rod k downward, and cause pawl f to engage with the ratchet j with the same results as above described. lVith the latter construction the eye 6 willbe omitted fromthe take-up arm a.

Theinvention may also be applied with like advantage to a warpingmaehine.

Having thus described our invention. what we claim as new, and desire to secure by Letters Patent, is

1. The combination, with the bobbin-spindle provided with a ratchet-wheel, means for operating said spindle, and apivoted pawl adjacent to but normally out of contact with said ratchet'wheel, of the creel-spindle, the takeup loosely mounted thereon and provided with an arm extending parallel with said spindle to bear 011 the thread being wound, and a eon-e nection, substantially as described, secured at one end to the pawl and extending at its opposite end to the take-up arm to be operated thereby, whereby when a thread breaks the said arm will fall, move the connection longitudinally, and throw the pawl into engagement with the ratchet-wheel, substantially as set forth.

2. The combination, with the bobbin-spindle having a ratchet-wheel, means for operating the spindle, and the pawl f, having along arm extended adjacent to the said ratchetwheel, and a short arm, of the cree1-spindle Z), a takeup loosely mounted thereon and provided with an arm. a, extended parallel with the said creel-spindle and adapted to bear on the thread being wound, and a cord, d, connected to the short arm of the pawl and to the arm a of the take-up, substantially'as set forth.

3. The combination, with the bobbin-spindle B, having a ratchet-wheel, means for op erating the spindle, and the pawl f, normally out of contact with the said ratchet-wheel, of the series of creel spindles I), the take-ups A, loosely mounted on said spindles, and each having an arm, a, extended parallel with the creel-spindles and provided with eyes a, and a series of cords, d, all secured at their upper ends to the pawl, and each secured at their lower ends to an eye, 6, substantially as set forth.
